Saro is the leader of a group of monsters that roam the lands of Burland,
Santeem, and other kingdoms in the same general vicinity. Being half human
and half elf, he fell in love with an elf named Rosa--he built her a town
in her name (Rosaville) and appointed one of his best Knights as her personal
bodyguard. Over time, dwarves started to migrate to Rosaville and eventually
formed the base population of the town; as humans continued to shun monsters
and build their towns and castles without regard for the habitats of monsters,
Saro found himself more and more isolated from his human roots.

Saro entered a fighting tournament in the Kingdom of Endor, and almost won the
tournament and control of the Kingdom when Alena, the Princess of Santeem,
began to pose a threat to his seemingly certain victory. Rather than stay to
fight Alena, Saro disappeared from Endor; shortly after, the people of Santeem
disappeared without a trace. Linking the disappearance of her people to that
of Saro, Alena and her companions set out to find him and settle their issues
once and for all.

But Saro was nowhere to be found; as time passed, he continued to dislike
humans even more due to the way they treated the monsters. He vowed to help
the monsters regain their prominence in the land by conquering the humans,
one kingdom at a time. He worked diligently to achieve this goal, to the
point where even Rosa tried to talk him out of it. She was unsuccessful in
her attempts.

Eventually, a rumor about elves crying ruby teardrops began to spread; humans
then began hunting elves for their teardrops. Rosa was captured in time, and
the humans beat her to death trying to get ruby teardrops from her. Upon
hearing this, Saro's hatred towards humans increased a thousandfold--he changed
his goal from conquering the humans to killing them.

Absolutely livid, Saro began researching a notion called the "Secret of
Evolution" which in theory would allow him to evolve into an omnipotent
being. He gathered the various artifacts required for the evolution process,
and set out to begin the evolution; as a precautionary measure, he secluded
himself in the isolated Dire Palace. His appearance changed over time as he
became more powerful and evolved slowly into Necrosaro--after the Chosen Ones
defeated Esturk, the Ruler of Evil, Necrosaro took over as the New Ruler of
Evil. He made his way to the Dark World, and the Chosen Ones followed him
there. In an epic battle, the eight Chosen Ones defeated Necrosaro, releasing
his vengeful soul and reuniting him with his love, Rosa.
